Robert I. Nesmith (1891-1972) was a numismatist, photographer, and an authority on treasure hunting. He ran a photography
firm, R. I. Nesmith & Associates, in New York City and was chief photographer for Copper Commando, a newspaper published during
World War II that was devoted to demonstrating the importance of metal production to the war effort. He later owned and operated
a bookstore in Rye, New York, called The Foul Anchor, which specialized in books on treasure hunting. He became an associate
member of the American Numismatic Society in 1943 and a fellow in 1944.
Two scrapbooks of photographs and illustrations of coins struck at the Mexico City Mint, 1536-1556, and a list of documents
held by the Library of Congress that concern payments
made in pesos in Peru, 1531-1556.
